Sustainability.
Proven sustainability – for over 50 years.

Since the company was founded in 1973, responsible and sustainable behaviour has been a matter of course for RATIONAL and begins as early as the product development stage. Together with universities, we conduct research into resource-saving solutions.

Our commitment is reflected in our environmentally certified production; energy-efficient sales logistics; intelligent, low-energy, efficient buildings; regularly reviewed eco-audit according to DIN ISO 14001; and our return and recycling program for our old appliances.

Significant reduction in resource footprint.

Our multi-functional cooking appliances contribute enormously to reducing the energy and resource footprint in industrial kitchens. This is underpinned by the project commissioned by the Zurich University of Applied Sciences:

"34 % less electricity and 53 % less water consumption with a choice are all arguments for the use of multi-functional cooking appliances in professional kitchens".

With RATIONAL cooking technology, you save on energy, water and raw ingredients and produce significantly less waste. This innovative cooking technology delivers maximum flexibility and power and meets the highest standards in cooking quality.

The results of the resource consumption analysis based on a before-after comparison speak for themselves: The cheapest form of energy is energy that we do not consume.

International certified.

We passionately care about the enviroment.
Three ISO certificates for Rational AG, confirming compliance with standards 9001:2015, 14001:2015, and 50001:2011, issued by DEKRA Certification GmbH.

Sustainable management is part of our daily routine, even in ecological view. We therefore continually review our energy and raw material consumption. In addition we have committed ourselves to meet the demands of the following ISO standards:

  • Quality management system: since 1996 according to ISO 9001
    We constantly improve our quality, streamline our processes and make them more efficient.
  • Environmental management system: since 2010 according to ISO 14001
    We constantly reduce our emissions and waste in order to be even more environmentally-friendly.
  • Energy management system: since 2016 according to ISO 50001
    We continuously improve our energy efficiency.

"Sustainable business and taking on responsibility for society have been integral elements of our business and production processes since the foundation of RATIONAL."
